Refer to the graphs, based on studies of the effects of pesticides on the tadpole immune system. in a laboratory experiment, wood frog (rana sylvatica) tadpoles were exposed to low or high concentrations of a pesticide, and then ribeiroia parasites. the tadpoles were then examined for (a) numbers of eosinophils and (b) numbers of ribeiroia cysts. error bars show one sd of the mean. compared with the control group, the frogs exposed to low concentrations of pesticides had about times as many parasite cysts.

i would suggest the best recommendation want to get out of the vehicle and look around to make sure their isn't anyone near or behind the vehicle.

explanation:

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.

all the above is what i would say

it means your tired?
